Specification forming part of Letters. Patent No. 3197,58 1, dated November 27,1877; application filed March'T, 1877.

To all whom it may concern: I

Be it known that I, EUGENE RANGAMAR, of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Steam-Motor for City Passenger-Gars; and I do hereby declare the follow-1' ing to be afull, clear, and exact descriptionof the same, reference bein g had a to the" action panying drawings, forming-partof this specification, in which--' i E'gure 1 is a plan view of the stationary boilers and a part of the road; Fig. 2 is an end view of thetstationary furnace and boilers. Fig. 3 is a plan of one form of iron truck. Fig. 4 is a side elevation of the same. f Fig. 5 is a side elevation of one of the longitudinal beams of the truck. Fig. 6 is an end elevation of the car-boiler and the beams shown in Fig; 5. Fig. 7 is a longitudinal vertical section of one form of the boiler. and furnace in, working" position in the car. Fig.8 is acrosssection of the same. Fig. 9 is an end view oi a boiler, showing one mode of cleaningthe fines. Figs. 10and 11 represent the grate and vessel for inserting and removing it. ,Fig. 12

.is a longitudinal vertical section, showing another forinof boiler; and Fig. 13 is a transverse verticalsection of the same.

Similar letters of reference in the accompa nying drawings denote the same parts.

The object of this invention is to provide for the public a street-car motorwhich shall present theadvantages of both steam and horsepower.

Without the disadvantages of either; or, in,

other words, a motor which shall render it practicable-to retain the present light and commodious form and internal arrangement of horse railroad-cars, andto run them economicall'y by steam-power without the necessityfor' ,a'fdummy or a separate locomotive, or for the services of a skilled engineer and-without noise, smoke, danger of explosion, or the 1 liability to frighten horses on the street.

fondly, in the co" struction and adaptation of the looilersand" be used in'carryin g branch pipes c c to a tu my first-mentioned improvement into practice and,-th1rdly,-m the details or subordinate arrangementsof mechanism herein shown and.

railroad-stations with water previously heated by means independent of the car, and keeping up this initial heat of the boiler-water by a furnace transported with the car; or, in other words, in supplying the feed-water, at or near the requisite heat and pressure. from a stationary boiler or furnace, and sustaining that heat and pressure subsequentl during the trip by the car boiler and furnace. My improvement is, therefore, on the one 4 hand, distinguished by the use of the car-furnace from the mereapplication hot water supplied from a stationary boile while, on

the other hand,' the application of the hot water from-a stationary furnace distinguishes it from the ordinary mode of supplying feed.-

water to locomotives and "other portable engines, it comprising neither all of the one process 1101' all, of the other, but only the combination of portions of youth, which obviates their'disadvantages and results in a new, practicable, and exceedingly valuable improve ment inthe art. a 1

"This part of any-invention is applicable to ferry-boats and other short-line conveyances.

I 3 The means by which I carry this part of my invention into practice are as follows: Along- I side of a track, A, of a city passengenrailway or other short-line railway,- I construct a furnace, B, and arrange in connection with it a boiler or boilers, O, fromwhich the feed-water is taken by any suitable means to the carboiler. I prefer-to employ two stationary boilare or tiers of boilers, C 0 both connected by be or nozzle, d, extending toward the track, each branch having a cock, 0 or c, which controls the flow of wa= ter' through it, The flues of thefurnace pass directly through the lower tier. Of-bczflerathen through the upper tier to thesmoke-stack, so that the" upper tier are heated by the waste heat not utilized in the. lower. tier, and the lower tier may be fed with water first heated by the upper boiler.

about 212 Fahrenheit 'in the upper tier, but to stand in the lower tier at about the same temperature and pressure as are required for the water in the car-boilers. In filling an empty car-boiler, the cock of branch 0 will first be opened and the car-boiler filled up to about the lower try-cock with water at 212 Fahrenheit after which the cock 0 will be closed and cock 0 opened, and the restrof the supply introduced from boilers G at a pressure of from fifty to seventy pounds, more or less, as may be required. D is a lever, and d a sliding coupling,

be readily efl'ected between the stationary boilers and the boiler of thecar, and said coupling may be provided with a bayonetrfastenin g or other lockih g device to prevent the steampressure from forcing the connection apart.

The boiler of the car, constructed and arranged in any suitable manner, being thus supplied with water at -the required temperature, fire is ffll'IliShBdLulK) it during the trip to I the next supply-station'by means of fuel burning in a furnace attachedto it. This furnace, also, may be of any suitable form and construction, and may be supplied from a reservoir of oil or hydrocarbon, of suitable fuel carried on the car; but; preferably, it 'is con-' structed for the burning of anthracite coal, and is supplied witlntincandescent coal from the stationary furnace B at the beginning. of each trip, so as to avoid all necessity for transporting the fuel 'or firing'up during'the trip. The amount of incandescent coal required will only be the small quantity requisite to keep up the steam at or near its initial pressure, or so that it shall not fall below the working pressure required, and hence the car-furnace may be made of comparatively small dimenslons, and will occupy but little room. Any form and arrangement of steam-engine that will-answer the purpose may be" employed in connection with the apparatus above referred to for driving the car. scription of the first part of my invention.

It will be seen that, by the apparatus'and system or process above described, in proportion as the quantity of water in the car-boiler r boils away and decreases and steam thereby makes faster, in almost the same proportion does the fuel in the furnace burn away and decrease in quantity and heating power, and thus counteract the tendency toincrcase of press ure, so that the car-boiler is rendered practically isothermal the pressure automatically adjusting, and-t e apparatus non-explosive. It will also be seen that all danger of the boilers running drywhile the fires are up, and of v the feed-water being'introduced upon red-hot surfaces, and of the steam-pressure being-raised to a'great and undue limit-the common causes of explosions-are by this systemavoided, and that the care and skill required with ordinary locomotives in attending to the conditionof the water and fire are rendered entirely unnecessary with my improved system.

' The water is to stand at as possible,

my invention consists in such arrangement,

' and engine adapted, when so arranged, to thepractical working of by which the connection can.

commodate itself must be surrounded, as far as practicable,

This completes thede- Although the-form and arrangement of the car boiler, furnace, and engines are notessential to the first part of my invention, which may be carried into successful practice by-many. different forms and arrangements thereof, yet

I give preference to a boiler, furnace, and en.- gines arranged under the body of the car, so that, substantially, the entire space inside of the carbody may be available for the seating ofpassengers or the storing of freight, and so that the presence and movements of the working machinery may be as completely concealed and, therefore, the second part of and in a boiler, furnace,

my system. 1 v For success ul use within the limited space available beneath the car, the boiler and furnace must have three peculiarities, viz., the boiler must be arranged horizontally to ac- ,tothe' space, thefurnace with the boiler-water, for. the purpose of-economjzing into which the heated air, gases and smoke first pass from the furnace must arranged so near the low-water line thatthere will be no danger of their exposure at any time while the fires are burning fiercely. These three fca' tures are all found combined in the second part of my'invention, and I have shown many 7 of the different modes in which they maybe practicallyembodied. In one of-these embodiments (represented in Figs. 7, 8, 9, 10, and

11) E is the horizontal boiler, arranged under the car G between the axles h of the tractionw i l, and F is the furnace, arrangethipside of the boiler, and having lines which, traverse the boiler, beneath or near the .iowwater line thereof, and discharge the smoke, -&c., into the smoke-stack at I. I prefer'to wheel H have the fines traverse'the boiler three times, as shown in Figs. 7 and 8, the smoke, 850.,

first passing-into the fines f at or near the low-water line, thence into a vertical flue, f

arranged within the boiler, to prevent waste of radiated heat, thence passing by other lines,

f, arranged as low as poss ble, to another vertical flue, f at the opposite end of the boiler, and thence, by a series of upper flues, f", to the smoke-stack; By this arrangement the heat passing into the smoke-fines is, to the fullest extent, utilized in making steam, and

none'of the fines that are liable to'become exserting the grate and burning coals into the heat, and the boiler-fines .or passages.

r with.

' in height, which will bring the'fiues ff always .i'urnaee at the beginning of the trip, as well as'for removing them when desired, is shown" at J in the form of a slotted bucket or pan provided with a handle. The grate is to be set into the pan and the latter filled with coals, when, by means of the handle-"the pan can be raised into/the furnace tilb'the grate registers with its bearings. The grate can then be locked in place and the panremoved. A draft-flue for theintroduction of air under the grate is shown at K, and is provided with a door or sliding plate at k to permit the introduction and removal of the grate and coals, and with a funnel shaped mouth, It, and damper or register k to enable the attendant to control and regulate the draft. With this furnace and boiler, the engine-cylinders are preferably arranged at the sides of the boiler, as shown at M, the pitmen 1 running to cranks p on the rear axle between the wheels.

'The exhaust N discharges into a chamber, 0,

of any suitable form, in which the exhauststeam iscondensed by means of blankets 0, wet, preferably with salt-brine, through which or in contact with which the steam is obliged.

to pass on its way to the smoke-stack; or any other suitable condensing apparatus may be substituted in place of the cloths; For the purpose of warming the cars in winter, a branch pipe, N, is connected to the exhaust-pipe, and extends to radiators or coils under the seats, or in any other suitable place in the car, and thence back to the exhaustpipe again, cocks at n being provided for the purpose of directing the exhaust steam through i the branch N in winter, or shutting it ofif there rom in summer. 4

vThe steam-dome is shown at Q, and the safety valve at Q, the various gages, cocks, levers, valves, 800., being arranged asusual.

A boiler of this class twenty-four inches high, thirty ,inches wide, and sixty-six inches long will contain about onehundred and fortyeight gallons, of which about sixty gallons will be evaporated in a trip of an hour and a half, this furnishing sufficient steam to sup-- ply two cylinders .of six'in'ches diametrand fourteen inches stroke, cut-oif-at one-half,and

having about eighty-eight. gallons of watersin f the boiler at the end of the trip. For sucha boiler the'furnace should be about ten inches underthe low-water line. a I x Various modifications of this boiler and-furnacemay be used, if preferred, of which I have shown onein Figs. 12 and 13, where! is a flatboiler, suitably stayed, and having a steamdome at t, and a transverse water-cylinder at T, communicating with the upper part of the boiler. 7

The furnace T is arranged in one end of v the waterchamber T so. as to leave a surrounding water-space, and the flues f pass directlythrough the other end of the chamber T, as shown inuFig. 13. A; pipe, t, may be arranged inside of theboiler, extending from the steam-dome to the opposite" end of the .ers G, substantially as described,

part T, so that when, on inclines, the water runs into either end of. the part T'the steam can readily pass to the dome t. This form of boiler has many advantages, being simple and cheap in construction, readily cleaned, economizing heat, and keepingall the flues submerged. The steam-dome may-be arranged at the end of thecar, projecting up through the platform.

With this form" of boiler the maybe employedas the driving-axle, the boiler and furnacebeing' arranged so far for-' ward as to bring the most of the weight thereon to increase the traction'of' the wheels, and

.the steamecylinder may be arranged in' any suitable position for applying the power, which, as above stated, may be communicated by means of cranks. applied at theouter ends of the axles, and screened from's'ight.

Whatever form andarrangement of boiler,

furnace, and engine. may be employed, 1 support all those parts-upon a strong'iron truck,

S, suitably braced in' every direction to resist the strains of the machinery and prevent the:

racking and dislocation-of the parts. 'Both axles are mounted in this truck, and the'car frameis so attachedto it as to bereadily detachable for the purpose of substituting an close car in winter, or an open one insum mer.

All the working m'achineryisto be boxed or otherwise screened from the sight of horses on the street. The wheels. notused as driv-r ing-wheels may be made to runloosely on their axles to facilitate the turning of' short 1 initial heat, during the trip or any part thereof,
